AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
400 PM PDT FRI OCT 23 2015

.SYNOPSIS...A BROAD AREA OF HIGH PRESSURE WILL MAINTAIN DRY AND WARM
CONDITIONS ACROSS NORTHWEST CALIFORNIA THROUGH SATURDAY. A LOW
PRESSURE SYSTEM WILL BRING THE NEXT CHANCE FOR RAIN LATE THIS
WEEKEND...MAINLY IN THE NORTH.

&&

.SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)...AN UPPER LEVEL RIDGE
OVER THE WEST COAST WILL MAINTAIN DRY AND WARM CONDITIONS OVER
NORTHWEST CALIFORNIA THROUGH SATURDAY. HIGH CLOUDS HAVE BEEN
SPREADING OVER THE REGION TODAY AHEAD OF AN APPROACHING SYSTEM
DEVELOPING OVER THE EASTERN PACIFIC. MODELS CONTINUE TO PROG A
LOW CUTTING OFF FROM THE MEAN FLOW AND MOVING TOWARDS NORTHWEST
CALIFORNIA SATURDAY NIGHT INTO SUNDAY...DRAGGING A COLD FRONT
THROUGH THE AREA AND BRINGING RAIN TO AREAS GENERALLY NORTH OF
MENDOCINO COUNTY. AS THE FRONT SWINGS THROUGH THE
AREA...INSTABILITY IS PRESENT NORTH AND WEST OF THE WATERS. HAVE
NOT INTRODUCED THUNDER INTO THE FORECAST ATTM...ALTHOUGH IT IS
SOMETHING TO WATCH OVER THE NEXT COUPLE OF DAYS. ALL MODELS ARE
IN AGREEMENT THAT RAIN WILL FALL ACROSS A GOOD PORTION OF THE
AREA...WITH THE HIGHEST AMOUNTS ACROSS DEL NORTE COUNTY (0.25 TO
0.75 INCHES)...AND LESSER AMOUNTS TO THE SOUTH AND EAST. WHERE
MODELS DIFFER IN THIS SOLUTION IS THE AMOUNT OF RAIN...AND HOW
LONG POST FRONTAL SHOWERS PERSIST. THE GFS AND ECMWF HAVE SHOWERS
ENDING BY EARLY MONDAY WITH SHORT WAVE RIDGING BUILDING OVER THE
AREA...WHILE THE NAM12 HAS SHOWERS CONTINUING THROUGH THE DAY
MONDAY ACROSS THE FAR NORTH.

THE INCREASE IN CLOUD COVER TODAY INTO TONIGHT SHOULD LIMIT
RADIATIONAL COOLING...BETTER RESTRICTING FROST FORMATION IN THE
VALLEYS OF TRINITY COUNTY. STILL...LOW TEMPERATURES MAY FALL INTO
THE MID TO UPPER 30S IN A FEW OF THE COLDER LOCATIONS AGAIN
SATURDAY MORNING. STP

&&

.LONG TERM (TUESDAY THROUGH FRIDAY)...AN UPPER RIDGE OVER THE REGION
EARLY TUESDAY WILL BRING A FAIR START TO THE EARLY MORNING HOURS.
HOWEVER, MODELS ARE IN GOOD AGREEMENT WITH THE RIDGE SHIFTING EAST,
ALLOWING A DEEPENING UPPER TROUGH TO APPROACH THE COAST. THE SURFACE
REFLECTION OF THIS SYSTEM WILL BE A COLD FRONT ENCROACHING UPON NW
CAL. THIS SYSTEM IS FORECAST TO BRING RAIN TO THE REGION. MOISTURE
FROM A TROPICAL SYSTEM, OLAF, IS EXPECTED TO BECOME ENTRAINED INTO
THIS NORTH PACIFIC PATTERN POTENTIALLY CAUSING MORE PRECIPITATION
THAN MODELS ARE NOW INDICATING. MODELS ARE IN GOOD AGREEMENT WITH
THE OVERALL PATTEN, SO HAVE INCREASED POPS FOR MIDWEEK, LATE TUESDAY
THROUGH WEDNESDAY. APART FROM THIS, THERE WERE VERY FEW CHANGES TO
THE ONGOING FORECAST. A DRYING TREND IS EXPECTED LATE NEXT WEEK.
BFG

&&

.AVIATION...VFR AT AREA AIRPORTS IS EXPECTED TO REMAIN INTO THE
EVENING HOURS. AT THE COAST LOW CLOUDS WILL LIKELY REDEVELOP
TONIGHT, CAUSING MVFR AND POSSIBLY PERIODS OF IFR. VSBY SHOULD NOT
BE THE PROBLEM TONIGHT DUE TO AN APPROACHING TROUGH, KEEPING THE
LOWER ATMOSPHERE VERTICALLY MIXED. IF VSBY DOES DROP IT WILL OCCUR
DURING THE EARLY PART OF THE NIGHT AS ANY SHORTWAVE RIDGING PASSES.
INTERIOR LOCATIONS SHOULD REMAIN VFR. BFG

&&

.MARINE...CONDITIONS WILL CONTINUE TO SUBSIDE TONIGHT. MODELS HAVE
BEEN TOO FAST TO BRING THEM DOWN THROUGH THE DAY TODAY, BUT
OBSERVATIONS HAVE FINALLY BEGUN TO SHOW A DOWNWARD TREND. AS SUCH,
HAVE ALLOWED ALL SMALL CRAFT ADVISORIES TO EXPIRE AT 3 PM. WITH AN
APPROACHING FRONT FOR THE WEEKEND, SOUTHERLY WINDS AND WAVES WILL
INCREASE, CAUSING THE LIKELIHOOD OF MORE SMALL CRAFT ADVISORIES TO
BE HOISTED. THIS WILL BE FOLLOWED CLOSELY BY A POST FRONTAL SWELL
ARRIVING IN THE NW CAL WATERS. SWELL IS EXPECTED TO BE ABOVE 10 FT,
WHICH PUTS IT IN TO SMALL CRAFT ADVISORY REALM. SEAS WILL REMAIN
ELEVATED AT LEAST IN TO THE MIDDLE PART OF NEXT WEEK. OVERALL, LOOK
FOR A LULL IN CONDITIONS TOMORROW (SATURDAY) THEN DETERIORATING
CONDITIONS FOR SUNDAY AND ELEVATED SEAS THROUGH THE WEEK. BFG

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...NONE.
